Selena Gomez

You have Taylor & Selena's exes, Joe Jonas & Nick Jonas, respectively, to thank for their first meetup. "We actually both met backstage at a Jonas Brothers concert," the brunette beauty explained on The Ellen Show. That was all the way back in 2008!

"Taylor and I dated Jonas Brothers together," she told the Herald Sun on a separate occasion. "We met when she was 18. I was 15 or 16. She was so great to me. Then we became best friends. She would fly out to see me when I was going through something really hard. We'd eat a lot of fattening food and vent."

Hayley Williams

Taylor & Hayley go all the way back to 2008, too — only, instead of JoBros, they have Tay's mama to credit for their initial friendship.

"We actually met at this Grammy party," Hayley told MTV News. "And her mom came up to us [Paramore] and was like, 'It's so nice to meet you guys, you've got to meet my daughter'... I think we exchanged numbers, and we started hanging out in Nashville not too long after that."

Emma Stone

Man, 2008 was a big year for T.Swift — and we're not just talking about the release of her second studio album, Fearless. It was also the same year she bumped into her future bestie, Emma.

"We met at the Young Hollywood Awards, it was for HollywoodLife," she told MTV News. "We met there 3 years ago, and then I listened to some of her music, and I wrote her an email saying I liked her music, I swear. And then we started talking and hanging out."

Hailee Steinfeld

And guess who just so happens to be the one to introduce Tay to Haiz...

Lily Aldridge

The Victoria's Secret Fashion Show didn't mark the first time Tay & Lil met. In fact, by the time T.Swizzle started performing at them, the two were already the best of friends.

So, how'd they meet? The VS Angel revealed on HuffPost Live, "Taylor is amazing. She's such a good friend. We both live in Nashville. She came to one of my husband's [Kings of Leon's Caleb Followill] concerts, and we found out we were neighbors, and then we became friends."

Karlie Kloss

Speaking of VS Angels, Taylor's friends with a bunch of 'em — and that bunch includes Karlie Kloss.

While the two gushed over each other on Twitter before they ever met IRL, there first face-to-face meeting happened thanks to a mutual friend. (HINT: We JUST mentioned her.)

"Taylor and I met at the Victoria's Secret Fashion Show 2 years ago," she dished in Glamour after their November 2013 meetup. "Lily Aldridge introduced us. She was like, 'Okay, you two are kindred spirits. How have my two nice American friends never met?' And that was it..."

Lorde

Prior to her first meeting with Taylor, Lorde had actually spoken about her in an interview, saying she wasn't a good role model because she's too "perfect." Soon after the quote made headlines, Taylor sent Lorde flowers after one of her shows. From then on, there was no bad blood. In fact, Taylor didn't even know Lorde had spoken about her beforehand.

"We met up here in New York" in 2014, she said on The Tonight Show with Jimmy Fallon. "We had Shake Shack, which I feel like is kind of a good bonding... a friendship like bonds with those thick-ass milkshakes."

Camila Cabello

The Fifth Harmony singer's friendship with the "Out of the Woods" crooner may not go back as far as Selena's or Hailee's, but she's definitely a major part of the crew.

The pair first met back in August 2014, courtesy of a little show called the MTV Video Music Awards.

"She probably doesn't even remember this," Camila told Teen Vogue. "But the first time we met at a VMA party, the first thing I asked her about was songwriting advice." Aww.

LOL
